LGTM, thanks!

@amckinley Would you mind fixing the DCO in the commit, please?

[pracucci]

@amckinley Sorry for the troubles, but DCO is still failing, because only 1 out of 4 commits have been signed off. An option to fix it would be squashing the commits:

git rebase -i HEAD~4

Then, in the edit, keep the 1st commit as is (do not edit it), while the change the action for the 3 remaining commits to s (it stands for "squash"). Once saved & exited, you will be prompted with another editor to update the commit message. Make sure it will have Signed-off-by: Austin McKinley <[email protected]>

Thanks!

@pracucci no problem; my mistake. Should be good to go now.
